Iran vs Türkiye, explained
Today Iran is the larger of the two, with about 92.8 million people against Türkiye's 87.8 million. Iran is the world's 17th most populous country and Türkiye the 18th.
Their paths to 2100 differ. Iran declines over the century, moving from about 91.1 million to 80.3 million (-11.9%). Türkiye falls sharply, going from 87.4 million to 65.7 million (-24.8%).
The order does not flip this century: Iran is still the larger of the two in 2100. The two trajectories run in parallel rather than crossing.
The deeper contrast is age and fertility. Iran has a median age near 33 and 1.68 births per woman, against Türkiye's 33 and 1.62. All figures follow the UN's medium-variant projection.
